Parent: Object

The Mail class represents an internet mail message (as per RFC822, RFC2822) with headers and a body.

Public Class methods

new(f)

Create a new Mail where f is either a stream which responds to gets(), or a path to a file. If f is a path it will be opened.

The whole message is read so it can be made available through the header, #[] and body methods.

The "From " line is ignored if the mail is in mbox format.
